networkSecurity.lastKeyServer |
According to the BACnet protocol documentation:
Specifies the device identifier and address of the last Key Server that successfully updated a security key in the device. If no Key Server has updated the keys sets in the device, the deviceidentifier field shall contain 4194303 in the instance part, the network-number field shall be 0, and the mac-address field shall be empty. This property is writable in order to allow a Key Server address to be provided to the secure device before it has received a Device-Master key. This allows the secure device to be directed to the Key Server in a legacy environment where globally broadcast Request-Key-Update messages will not be routed. A device may make this property read-only once a Device-Master key has been received.
Property lastKeyServer of object networkSecurity can be read and written using a block tag with 3 elements.
